How do I make a pour-over with a glass dripper?

The glass dripper is a classic piece of coffee gear that offers a clean, elegant way to brew. Because glass is non-porous and neutral, it doesn't impart any flavor to the coffee, allowing the true character of the beans to shine through. Whether you are using a V60, a Chemex, or another glass cone, the technique remains largely the same: it is all about controlling the flow of water through the coffee bed.

Start by folding your paper filter and placing it in the dripper. It is crucial to rinse the filter with hot water before adding your coffee. This serves two purposes: it warms up the glass dripper and the carafe below, and it removes any 'papery' taste from the filter. Discard the rinse water before you begin your brew. This simple step is a hallmark of good brewing technique and significantly improves the final cup.

Next, add your coffee. A medium-fine grind—similar to the texture of sea salt—is usually the best starting point. Level the bed of coffee and create a small indentation in the center. Start your timer and pour just enough water to saturate the grounds, usually about twice the weight of the coffee. This is the 'bloom.' You will see the coffee bubble and rise as it releases carbon dioxide. Let this sit for 30 to 45 seconds.

After the bloom, continue pouring the remaining water in slow, steady, concentric circles. Avoid pouring directly onto the sides of the filter, as this allows water to bypass the coffee grounds, leading to a weak, watery cup. The goal is to keep the water level consistent and the coffee bed evenly saturated. The entire process should take between 2.5 and 4 minutes, depending on your specific dripper and grind size.

In practice, the glass dripper is a forgiving and rewarding method. If your coffee tastes too strong or bitter, try a slightly coarser grind next time. If it tastes weak or sour, try a finer grind. Because you can see the coffee through the glass, you can observe the extraction process in real-time, which helps you learn how different grind sizes and pour speeds affect the final result. It is a tactile, meditative way to start your morning.
